(b) 31.9

Step-by-step explanation

We know that

$a^{2} =b^{2} +c^{2}-2bccosA$

we put the value of a, b,c in above equation and then solve.

$24^{2}= 35^{2} +45^{2} -2*35*45*cosA\\576=1225+2025-3150cosA\\576=3250-3150cosA\\576-3250=-3150cosA\\-2674=-3150cosA\\cosA=\frac{-2674}{-3150}\\ cosA=0.848\\A=arccos(0.849)\\\\A=31.9$

Hence the required angle is 31.9 degree.
